ROBERT XV. HUNTON, OF NEWTON, MASSACHUSETTS KNO 'l'TER.

SPECIFIGATION formingpart of Letters Patent No. 745,623, dated December1, 1903.

I Application filed April 23, 1903. Serial No. 153,958. (No model.)

To all whom it may concern.-

Be it known that I, ROBERT, W. HUNTON, of Newton Upper Falls, in thecounty of Middlesex and State of Massachusetts, have invented a new anduseful Improvement in Knotters, of which the following is a full, clear,and exact description, reference being had to the accompanying drawings,forming a part of this specification, in explaining its nature.

My invention relates to a knotter or knottying tool especially designedfor tying spindle-hands, so called, which are used in spinningmachinesfor communicatingto the spindle the motion of their driving drum orpulley. These bands are made with a loop at one end, into which anotherpart or end of the band is knotted, and which knot is customarily tiedagainst the whirl of the spindle, around which the band is passed afterbeing passed around the dri ving-drum. This knotting or tying of theband around the whirl of the spindle has always been done by hand,

and instead of being done uniformly and with precision it usually hasbeen done, owing to the unskill'ulness or indifference of employees, inan inexact and neglectful manner, with little regard to the certainty ofthe knot or the proper tension of the band, and in a manner oftentimesthat would leave the knot to project on the inside of the band tocontact with the whirl of the spindle or the drum as it traveled aroundthem, and resulting, of course, in an unevenness of motion, if notactual displacement of the band.

By my invention I have devised a means by which the personal equation ofthe employee is for the most part eliminated, and the knot can be tiedquickly, with certainty, and with almost mechanical regularity andprecision, and in a manner by which a proper tension of the band issecured, and so that the knot comes on the outside of the hand, leavinga continuous even surface to bear in the running against the whirl ofthe spindle and its driving-drum. The means comprises a knot-tying toolof the character specified, the formation and capability of which canbest be seen and understood by reference to the drawings, wherein-Figure 1 shows my improved knot'tying tool in elevation.

Fig. 2 shows a detail of jaw a at the point a the tools structure towhich reference will hereinafter be made. Fig. 3shows in elevation amodificationthereof. Figs. 4 to 7, inclusive, show in elevation variousstages of operation when the tool is applied to the tying of a knot, aswill hereinafter be referred to in detail. Fig. 8 shows in elevation acompleted knot which my knotter is especially adapted and designed totie.

In the drawings the knotting-tool is represented as made of two parts ormembers A A, which members hear such pivoted relation to each other asto form the opposing jaws a a and the lever-handles a a respectively.tained by the member A being formed to extend through a slot a cutlongitudinally through the member A, with a pin a forming the pivotalpoint of fulcrumage. Both members are best formed substantially asshown, and especially so in order to obtain a proper jointure of theopposing jaws a a. The jaws are made relatively long and slender, thejaw a, being made especially thin, and they combine when closed to forma nose or beak of almost cone-shaped conformation, with one or the otherof said jaws being extended to form the point thereof, in Fig. l the jawa of the member A having such extension, while in Fig. 3 in modifiedstructure the jaw a of the member A is so extended. The jaw a is madesubstantially as shown, somewhat rounding, narrowing toward its end, andwith a longitudinally-grooved interior in which the jaw a partially lieswhen shut and whereby both jaws combined present substantially arounding or cone-shaped conformation, like as before referred to. Thelever-handles a a may have any suitable shape whereby the tool may bestbe manipulated.

In Fig. 3 I have shown the handle a of the member A as provided with ahook a, by

which the tool may be attached to the gar ment of the wearer so as to bereadily accessible. In Fig. 3 I have utilized the scissorlike action'ofthe jaws do by forming a cutter thereon, which is done,-as shown, byforming a cutting-blade a in the backof the jaw a near its point offulcrumage, which is made to engage when the jaw is closed with the Aproper pivotal connection is ob- This particular for.

mation of the cutter and even its use is entirely arbitrary. It forms,however, a convenient instrument in combination with the other parts, aswill hereinafter appear.

The operation of knotting the spindle-band (designated 13) and thecapabilities of the knotting-tool just described are as follows:Assuming the band to have been passed around the drum and in position tobe tied against the whirl of the spindle, the nose or band of theknotter is first carried through the loop 1), formed in the end of theband, (see Fig. 4,) and sufficiently to enable the opposing jaws beyondthe loop to grasp a portion of the free end b of the band, (see Fig. 5,)the tool then being held firmly against the edge of the whirl and thejaws grasping such section of the free end of the band as is mostconvenient, and it is especially to be noted at this point the facilitywith whichthis initial feature of the operation is performed, both withrespect to the spreading and holding of the loop end of the band and thecapability of the device to grasp and hold the band at its free end, asit were, and even when the band is drawn with some considerable tension.After the jaws have grasped a portion of the free end b this 1 portionof the cord is drawn through the loop holding the end of the loop.

Z), when the loop b is formed, (see Fig. 6,) with the jaws of theknotter, of course, still holding the end thereof. The knotter is thenturned and a portion of the freeend of the band is then laid over thesecond loop I), (see Fig. 6,) beneath the nose of the knotter inposition to be forced through the loop by the nose, so that it may betaken hold of and drawn through by hand, the knotter still (See Fig. 6.)After being drawn through the loop Z), (see Fig. 7,) the free end b ofthe band is then drawn taut by hand, shortening the said loop, and theknotter traveling withit is moved up to the edge of the whirl, its jawstill holding onto theloop. The knot is now substantially formed. Stillholding the free end of the band taut the knotter is let go its holdupon the loop I) and the knot is fully formed, (see Fig. 8,) and withthe release of the knotter the tension of the band around the whirl andthe drum is still further increased by the fu rther tightening of theknot, this being effected by the knot slipping up to draw tighter whenthe knotter is released, which overto the slenderness of theknotting-jaws.

comes any tendency to loosening or reduction of tension at this time,this lessening at any rate being reduced to a minimum owing The looseend of the band is then cut off close to the knot, which may be done togood advantage by such cutter as that formed between the back end of thejaws a a, as before described.

By means of suchan instrument and in the manner I have described theends of the spindle-band can be knotted quickly, with certainty, andwith almost mechanical regularity and precision, and in a manner bywhich a proper tens-ion of the band is secured, and so that the knotalways comes on the outside of the band, (see Fig. 8,) leaving acontinuous even surface to bear in the running against the Whirl anddrum.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States 1; In a device of the characterspecified, members pivotally combined and forming lever-handles andslender narrowing jaws actuated thereby, one of which jaws is extendedbeyond the other to form a pointed nose or beak, substantially as andfor the purposes set forth.

2. In a device of the character specified, members pivotally combined,and forming lever-handles, and slender narrowing jaws actuated thereby,one of which jaws extends beyond the other, substantially as described.

3. In a device of the character specified, members pivotally combinedand forming lever-handles, slender narrowingjaws actuated thereby, oneof which jaws is formed roundingwithalongitudinally-groovedinteriorintowhich the other of said jaws is adapted to lie when the jaws are closed,and one of which jaws is extended beyond the other to form a pointednose or beak.

4c. In a device of the character specified, members pivotally combinedand forming lever-handles, and slender narrowing jaws actuated thereby,one of which jaws is extended to form a beak and a cutter formed on saidjaws, substantially as described.
